The Starrett-Webber RS81 is an 81-piece English rectangular steel gage block system from one of the most established names in precision dimensional standards, and the natural choice for customers who specify Starrett-Webber.

Choosing a Grade

Grade B is the shop-floor reference set — broad dimensional capability combined with the Starrett-Webber name, sitting between economy workshop sets and considerably more expensive inspection-grade systems.

AS-1 is the premium choice, combining the same extensive 81-piece English configuration with inspection-grade accuracy and a certificate of calibration. It is appropriate for customers running professional dimensional inspection, calibration and quality-control work rather than shop-floor setting.

Calibration and Traceability

Gage blocks are the reference standards other instruments are set against, so their own calibration status governs the credibility of everything measured with them. WESTport provides ISO/IEC 17025 accredited calibration to keep a set documented and controlled over its working life.

Applications

Machine shops and inspection departments needing broad dimensional capability, and sophisticated quality departments that specify Starrett-Webber dimensional standards.
